Title: Whey prodn. from skimmed milk together with casein - comprising concentrating protein before precipitating casein with acid milk product
IPC: A23C21/00
Filed: 1975-11-20
Abstract: A process for making whey or whey products from skimmed milk or mixtures with other milk liquids at the same time producing casein comprises first bringing the skimmed milk or mixture to a regulated protein content by increasing the protein content by >=10%. The casein is then pptd. as a clot by adding a liquid of milk origin the pH of which has been reduced by cation exchange. The clot of casein is sepd. from the whey and the casein is recovered from the clot and the whey can be transformed into whey products. They whey is used in human and animal foods. The regulation of the protein content ensures constancy in processing and in product quality. Process reduces the loss of fine casein in the whey and gives a better quality whey product. The process is simpler than those previously suggested and require less plant.
